Stoddart-Mattson-Kibbey Carboniferous Isopach and Lithofacies Map

Stoddart/Mattson/Kibbey Isopach and Lithofacies GIS data contains line features representing subsurface geological formations from the Carboniferous period in the Western Canada Sedimentary Basin. The dataset was created by the Alberta Geological Survey from archived digital files produced in the mid-1990s and later edited in 2005-06. It is part of the Geological Atlas of the Western Canada Sedimentary Basin, specifically Chapter 14, Figure 35.

Use Cases

• Model subsurface rock thickness (isopach) using line feature geometry and attributes for basin analysis.
• Analyze spatial distribution of rock types (lithofacies) from attributed line features to understand depositional environments.
• Integrate isopach and lithofacies line features with other geological layers for 3D basin modeling and resource assessment.

Strengths

• Data is part of an authoritative reference volume, the Geological Atlas of the Western Canada Sedimentary Basin.
• Shapefiles were consolidated and attributed into single files by feature type for usability.

Limitations

• Original digital files were created in the mid-1990s, potentially using outdated methodologies.
• Specific row counts, column details, and sample data are unavailable for assessment.

Provenance

Alberta Geological Survey, Government of Alberta.

Collection Method

Produced from archived digital files, later edited to correct, attribute, and consolidate into shapefiles.

Time Range

Geological data represents the Carboniferous period.

Freshness

Data was last updated on the platform in March 2026, though the underlying data creation and editing occurred between the mid-1990s and 2006.
